keyword=running shift summary
start of shift, running PY-1C.
run 1412 ... 4He target ... PY-1C kinematics ...
run 1413 ... 12C target, raster off ... 12C pointing run ... oops, bad prescale factors
run 1414 ... 12C target, raster off ... 12C pointing run
run 1415 ... 12C target, raster off ... 12C pointing run ... ROC14 problems, run killed .................... halfway ... both ROC2 and ROC14 required rebooting.
run 1416 ... 12C target, raster off ... 12C pointing run ... good run.
now switch to 10cm dummy ...
run 1417 ... 10cm target, raster on, spot 4x4, dummy run... good run
run 1418 ... 10cm target, raster on, dummy run ... good run
run 1419 ... 10cm target, raster on, dummy run ... good run.
... at 2:37, start change to PY-1B kinematics on SR only, SL remains
...... at PY-1C setting for link measurement.
3:07 right spectrometer at 52.42, right dipole set for 0.86990 GeV/c
....... switched to 4He target
3:10 accerator injector efficiency test .. beam down
run 1420 ... 4He target, raster on, linking run ... good run
run 1421 ... 4He target, raster on, linking run ... good run
...... move SL to PY-1B setting
...... changed left spectrometer mom setting to 2.020 GeV/c (cycled Q2, Q3)
...... changed trigger coin to 0.8699 setting
run 1422 ... 4He target, raster on, production run ... trigger setting not
...... optimal, changing it.
run 1423 ... changing trigger setting during run, junk
...... trigger setting at 875-1170 range
run 1424 ... 4He target, PY-1B kinematics, raster on, production run ... good run
run 1425 ... 4He target, PY-1B kinematics, production run
run 1426 ... 12C pointing run, PY-1B kinematics ... good run

now switch to 10cm dummy ...
run 1428 ... 10cm target, raster on, spot 4x4, dummy run... good run
... at 6:25, start change to PY-1A kinematics on SR only, SL remains
...... at PY-1B setting for link measurement.
6:35 accelerator tuning beam
run 1429 ... 4He target, raster on, linking run ... good run
run 1430 ... 4He target, raster on, linking run ... good run
...... move SL to PY-1A setting
...... changed left spectrometer mom setting to 2.105 GeV/c (cycled Q2, Q3)
...... changed trigger coin to 710-875 setting
run 1431 ... 4He - junk run to confirm coin window is OK
run 1432 ... 4He target, PY-1A kinematics, raster on, production run ... beam tripped out at end
run 1433 ... 4He target, PY-1A kinematics, raster on, production run ... good run
